Yeah with a docker container running 24/7 and a phone app it’s much better. they also have a setting where deleted files on phone are simply moved to archive on the server.

Having setup both, ive found syncthing to be much simpler. I would probably not go through the headache of setting up https and databases for next cloud again…

How can you ever learn the risks of exposing ports if all answers are “if you don’t know you shouldn’t do it”?

The post explicitly recommends ONLY exposing the wireguard port, not 80/443/22 which one should usually not do anyways. Very different things!
